Summary

The aim of this study is to investigate the effects of shoulder eccentric exercise training on shoulder mobility, rotator cuff strength, pain and dysfunction, scapular kinematics and muscle activation in symptomatic overhead athletes with posterior shoulder tightness.

Detailed description

Overhead athletes commonly have posterior shoulder tightness due to repetitively high tensile loading during overhead throwing. However, intervention studies focused on posterior shoulder tightness in people with subacromial pain are still limited. Additionally, eccentric exercise was thought to improve the eccentric strength and neuromuscular control of posterior shoulder muscles to endure repetitively eccentric loading, which may improve posterior shoulder tightness and decrease the risk of subacromial pain. Nevertheless, no previous study investigated the influence of eccentric exercise on posterior shoulder tightness in overhead athletes. The aim of this study is to investigate the effects of shoulder eccentric exercise training on shoulder mobility, rotator cuff strength, pain and dysfunction, scapular kinematics and muscle activation in symptomatic overhead athletes with posterior shoulder tightness.
